dear all,
how could i delete the same observation in the data set?
for example
name, 20001, 200002
aaa,1,1
aaa,1,1
aaa,1,2
bbb,1,2
how do I only keep one 'aaa,1,1' in the dataset and get the following data
name, 20001, 200002
aaa,1,1
aaa,1,2
bbb,1,2
Could you please give me some suggestion?
many thanks in advance.
